Abstract
Conductance G of a 2DEG-Superconductor (S) device in a high magnetic field is studied: G(ν) is calculated. When the
cyclotron diameter in 2DEG is larger than the width of the 2DEG-S surface then G(ν) becomes nonmonotonous function due
to the Aharonov-Bohm type interference of quasiparticles at the surface. At certain parameters of the junction the
conductance oscillates with ν.
